What is two-step verification?
Many of your online accounts or software applications are currently protected by a login and password. That password is the single factor in the authentication process — the way that those applications or services confirm your identity. Unfortunately, passwords are easily stolen or hacked, which means that the accounts and data behind those passwords are at risk.
Two-step verification adds at least one more layer of identity verification to that process so your protection against hacking and fraud attempts is stronger and more secure than a simple password. That additional factor can take many forms, such as a physical ID card, a digital confirmation code, or even your fingerprint. You're using two-step verification every time you pay a transaction using a debit card or when you withdraw cash from an ATM: your PIN is one factor and the card itself is another.
